神经科学是一个神经科学.
计算生物学计算生物学
动物行为动物行为

背景情况:

感官适应是与重复刺激的神经反应的减少.
对适应的行为反应可能有所不同 (习惯性,不变性),这表明神经与行为之间存在灵活的联系.

研究的目的:

研究神经适应在行为决策中的灵活转化.
开发一个数学框架,以在多个时间尺度上进行最佳的感官编码和表示.

主要方法:

为最佳的感官编码创建了一个数学框架.

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
